| − | *Rare cause of chronic [[Liver - Anatomy & Physiology|liver]] failure in young dogs
| |
| − | *Less than 5yrs of age
| |
| − | *Standard poodle overrepresented
| |
| − | *Gross findings:
| |
| − | **Micronodular microhepatica, ascites, numerous portosystemic shunts
| |
| − | *Histology:
| |
| − | **Hepatic architecture disrupted by collagen and reticulin fibres separating the hepatic lobules into small clusters and individual cells
| |
| − | **Hepatocytes mutlifocally swollen, lightly eosinophilic, some binucleated.
| |
| − | **Variable nodular regeneration.
| |
| − | **Scattered necrotic cells and occasional foci of inflammation.
| |
| − | *Cu2+ accumulation not a consistent finding.
| |
| − | *Aetiology – possibly a specific reaction pattern in neonatal/juvenile [[Liver - Anatomy & Physiology|liver]] .
| |
| − | *Differentials:
| |

| − | *2 main types
| |
| − | **cholangiohepatitis
| |
| − | ***cholangitis
| |
| − | ***periportal hepatocellular necrosis
| |
| − | ***neutrophils in the portal areas
| |
| − | ***acute or chronic.
| |
| − | ***Usually male, pure bred
| |
| − | *** Cats more ill than lymphocytic portal hepatitis.
| |
| − | ***Higher ALT and serum bilirubin levels.
| |
| − | **Lymphocytic portal hepatitis
| |
| − | ***infiltration of portal areas with lymphocytes and plasma cells
| |
| − | ***no cholangitis
| |
| − | ***no periportal hepatocellular necrosis.
